Title: Surface hardening method by precision casting
Inventor: KOBAYASHI KEIZO
IPC: C04B37/02
Filed: 1993-01-21
Abstract: PURPOSE:To easily and rapidly subject the surface of a casting material to a hardening treatment by coating the inside wall of the cavity of a casting mold for precision casting with >=1 kinds of the ceramic powders selected from ceramics of carbide, nitride, boride. CONSTITUTION:The powders of the ceramics of carbides, nitrides, boride are deposited on the inside wall of the cavity of the casting mold for precision casting. The deposition is executed by dispersing, for example, the ceramic powder into an org. solvent such as ethyl alcohol or water to prepare a slurry, pouring this slurry into the cavity of the casting mold, discharging the remaining liquid after standing for a required period of time and drying the inside of the cavity of the casting mold, thereby depositing the ceramic powder. Calcination is then executed usually in the atm. or nitrogen atmosphere. Finally, casting is executed by pouring the melt of active metals having a high m.p. such as titanium alloy and zirconium alloy into the cavity of such casting mold. The hardened layer is obtd. by a surface hardening method. This casting mold is appalicable to a precision casting method aiming near net shape molding.

Title: Judging method of injection molding and device thereof
Inventor: OWADA KENICHI
IPC: B29C45/77
Filed: 1994-02-24
Abstract: PURPOSE:To suitably judge the quality of injection molding by a method wherein the pressure deviation at a certain time point and the time deviation between the time point corresponding to the reference pressure, which is equal to the actual pressure, and the time point, at which the actual pressure is measured, are calculated. CONSTITUTION:A sensor 27 detects the resin pressure in a cavity 25. Firstly, the reference pattern on the change of the resin pressure in the cavity to the time is set. Next, the actual pressure pattern in the cavity 25 is detected. The pressure deviation between the actual pressure at a certain time point and the reference pressure corresponding to the time point is calculated. Next, the time deviation between the time point corresponding to the reference pressure, which is equal to the actual pressure, and the time point, at which the actual pressure is measured, is calculated. Further, when the pressure deviation exceeds the predetermined value and, at the same time, the number of times, at which the time deviation exceeds the predetermined value, is more than the predetermined number of times, molding is judged to be poor. Thus, the injection molding operation can be efficiently performed, since the allowable range of the actual in-mold pressure is set properly.

Abstract: PURPOSE:To obtain invariable optimum sound quality by allowing two heads to scane on the same track during after recording operation in the same position relation with recording operation. CONSTITUTION:During reproduction (Qs=0), pulse Pg from a pulse generating means 43 are passed through a shaping amplifier 91 and delayed through a delay circuit by time corresponding to width DELTAW/2 to be supplied to a comparing circuit 95 through a switch circuit 92.

Abstract: PURPOSE: To improve the stability of the combustion device by assuring the content of the data memory according to the program memorized by the fixed memory at the instant power failure.  
     CONSTITUTION: The memory in RAM209 of the micro-computer μ-p200 is maintained at the instant power failure by connecting the power source Vss, to which the condenser 15 is connected, to the voltage Vcc through the diode 16.

The voltage Vc105 of the condenser 15 stays Vss until t=t1, and the power source of μ-p200 is maintained normal. Therefore, if the instant power failure occures between t=t0 and t=t1, the normal RAM content of μ-p200 is maintained by inserting diode 16 and by accumulated charge of condenser 15, and μ-p200 operates normally after the power failure is recovered.
